Any good cocoa libraries that include both salt and IV AES Encryption?

I am just polishing up my encryption tool, but I noticed I am missing the salt, which is importnat in order to make the encryption more secure. I am using some built in cocoa methods, but they don\'t[详细]

CTR mode use of Initial Vector(IV)

from what I know, CTR mode doesn\'t use an Initial Vector. It just takes a counter, encrypts it with a given key and then XOR\'s the result with the plaintext in order to get the ciphertext.[详细]
